71802 ACD/HCP4DT 24 mm 15 mm 10 mm Frequently Asked Questions about 71802 ACD/HCP4DT Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 71802 ACD/HCP4DT over a 15 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
To safeguard CHG Bearing 71802 ACD/HCP4DT against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (15 mm x 24 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
The CHG Bearing 71802 ACD/HCP4DT is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
In its sealed configuration (Open Type), CHG Bearing pre-charges 71802 ACD/HCP4DT with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
